Graham McTavish also narratored/hosted a series of DVDs about The Hobbit and The Lord of the Rings. They were a cheap set, likely produced over in the UK back when Jackson's original trilogy was coming out. They basically just went through and retold each of the stories cliffnotes style, but were none the less entertaining and informative if you needed a quick refresher on the events of the books. Along with a little side info on Tolkein and his impact on literature.
